Title: Heat-resistant, non-combustible laminate
Inventor: GELDNER SIEGFRIED
IPC: B32B19/06
Filed: 1981-02-11
Abstract: The invention relates to a novel asbestos-free laminate which combines the properties of flexibility, insulation, air-tightness, high-temperature resistance and durability all in one. The laminate can be used in all technical applications where insulation against high temperatures is required as well as a shield against the passage of hot gases and, under these load conditions, there is also additionally a need to withstand or compensate for mechanical vibrations. Such load situations are frequently encountered in air-conditioning and ventilation, fire protection, the defence and air-raid defence sector and also in vehicle, ship and aircraft construction and space travel. The accompanying drawing shows an exemplary embodiment with an outer layer (1), which consists of non-combustible glass cloth, the inner side of which bears an air-tight and pressure-resistant metallised layer (2). The central layer (3) consists of an insulating ceramic fibre mat, the thickness of which varies and consequently the temperature resistance and insulating effect of the material can be established. The inner layer (4) consists of a flexible V4A steel-mesh netting and protects the material against mechanical penetration. <IMAGE>

Patent DE-3150149-A1 (DE)
Title: Vehicle propelled by muscle power
Inventor: LUTZ DIETER DR ING
IPC: B62M1/00
Filed: 1981-12-18
Abstract: By means of the vehicle according to the invention, which is propelled with muscle power, it becomes possible, as a consequence of the electronics designed for this purpose, to determine the performance delivered by the driver. For a predetermined travelling distance, the work expended or the time or the quantity of heat consumed for this distance can be displayed. Similarly, it is possible to carry out various training programmes, the effect of the training becoming apparent after repeated exercise. Sensible training programmes are impossible without the performance measurement in the vehicle, according to the invention, since external influences such as changeable wind conditions produce a different expenditure of work for the same distance. Therefore it is only by reference to the performance measurement that it is possible to ascertain whether there is a detectable training success after repeated exercise.

Patent DE-3215020-A1 (DE)
Title: Vacuum switch
Inventor: PETRY HANS DR ING
IPC: H01H33/664
Filed: 1982-04-22
Abstract: The invention relates to a vacuum switch whose switch contacts have conductor sections for splitting and guiding the switch current in the circumferential direction in order to produce an axial magnetic field. Circumferentially identical recesses (cross-section reductions as far as complete interruption) are incorporated into the contacts, between which recesses radial webs remain for carrying the current. The contacts, which are of identical construction, are not coincident with respect to the recesses but are installed rotated about the longitudinal axis. In this case, a web is covered by a recess of the other contact so that a touching contact surface is possible only between the recesses and the contact periphery. A gap is guided towards the contact edge from each recess in order to limit a conductor section in the circumferential direction. The mutually covering gaps of the contacts are placed where the recesses overlap in order to achieve a contact opening in the radial direction. The contacts are compact and easy to produce. Through-holes are suitable for the recesses.

Patent DE-3229276-A1 (DE)
Title: Melting furnace
Inventor: OHMORI TSUGUHARU
IPC: F27B14/06
Filed: 1982-08-05
Abstract: The refractory lining of an induction melting furnace (1) consists of two components (9,7). The component (9) is a prefabricated crucible which was produced outside the furnace by pressing to shape and sintering a fine refractory powder (SiO2). The component (7) is at first a loose, refractory, coarse-grained lining between the inner surface of the furnace and the crucible (9) and is mechanically compacted, with the crucible (9) partially acting as a mould. Due to the substantial freedom of the crucible (9) from pores and the fineness of the pores which are present, penetration of the molten metal into the crucible material is largely prevented and hence the life of the refractory lining of the melting furnace is extended. The coarse-grained component (7) of the lining also has a buffering function, which increases the resistance of the prefabricated crucible (9) to mechanical stresses. <IMAGE>
